SPORT mode indicatorlight (if so equipped)
This light illuminates and then turns off
when the ignition switch is placed in the ON
position, and when the SPORT mode is se-
lected.
For additional information, refer to “SPORT
mode switch” in the “Starting and driving”
section of this manual.
Turn signal/hazardindicator lights
The appropriate light flashes when the turn
signal switch is activated.
Both lights flash when the hazard switch is
turned on.
Vehicle Dynamic Control (VDC) OFF indicator light
This indicator light comes on when the
VDC OFF switch is pushed to off. This indi-
cates the VDC system has been turned off.
Push the VDC OFF switch again or restart
the engine and the system will operate normally. For additional information, refer
to “Vehicle Dynamic Control (VDC) system”
in the “Starting and driving” section of this
manual.
The VDC indicator light also comes on
when you place the ignition switch in the
ON position. The light will turn off af ter
about 2 seconds if the system is opera-
tional. If the light stays on or comes on
along with the
indicator light while
you are driving, have the VDC system
checked. It is recommended that you visit a
NISSAN dealer for this service.
While the VDC system is operating, you
might feel a slight vibration or hear the sys-
tem working when starting the vehicle or
accelerating, but this is normal.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear
warnings. When a disc brake pad requires
replacement, it makes a high pitched
scraping sound when the vehicle is in mo-
tion, whether or not the brake pedal is de-
pressed. Have the brakes checked as soon
as possible if the warning sound is heard.
Key reminder chime
A chime sounds if the driver’s door is
opened while the key is lef t in the ignition
switch. Remove the key and take it with you
when leaving the vehicle.
Light reminder chime
With the ignition switch placed in the OFF
position, a chime sounds when the driver’s
door is opened if the headlights or parking
lights are on.
Turn the headlight control switch off before
leaving the vehicle.
NISSAN Intelligent Key® door
buzzer (if so equipped)
The Intelligent Key door buzzer sounds if
any one of the following improper opera-
tions is found.
∙ The ignition switch is not returned to the LOCK position when locking the
doors.
∙ The Intelligent Key is lef t inside the ve- hicle when locking the doors.
∙ The Intelligent Key is taken outside the vehicle when operating the vehicle.
2-22Instruments and controls

– The battery of the tire pressure sen-sor is low.
∙ If the Easy-Fill Tire Alert does not op- erate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle.
As with any vehicle, loss of control could
result in a collision with other vehicles or
objects or cause the vehicle to roll over,
particularly if the loss of control causes
the vehicle to slide sideways. Be attentive at all times, and avoid driving
when tired. Never drive when under the in-
fluence of alcohol or drugs (including pre-
scription or over-the-counter drugs which
may cause drowsiness). Always wear your
seat belt as outlined in the “Safety – Seats,
seat belts and supplemental restraint sys-
tem” section of this manual, and also in-
struct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.
In a rollover crash,
an unbelted or improperly belted person
is significantly more likely to be injured
or killed than a person properly wearing
a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or lef t side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure be-
low. Please note that this procedure is only
a general guide. The vehicle must be driven
as appropriate based on the conditions of
the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes. 3. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course.
4. When appropriate, slowly release the accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while vehicle
speed is reduced. Do not attempt to
drive the vehicle back onto the road
surface until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires re-
turn to the road surface. When all tires
are on the road surface, steer the ve-
hicle to stay in the appropriate driving
lane.
∙ If you decide that it is not safe to re- turn the vehicle to the road surface
based on vehicle, road or traffic con-
ditions, gradually slow the vehicle to a
stop in a safe place off the road.

RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially
at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, refer
to “Wheels and tires” in the “Do-it-yourself ”
section of this manual. If a tire rapidly loses
air pressure or “blows-out” while driving,
maintain control of the vehicle by following
the procedure below. Please note that this
procedure is only a general guide. The ve-
hicle must be driven as appropriate based
on the conditions of the vehicle, road and
traffic.
WARNING
If there is a sudden loss of tire air pres-
sure, the vehicle will generally move or
pull in the direction of the flat tire. In this
situation, losing control of the vehicle
may cause a collision and result in per-
sonal injury.
To help avoid loss of control:
∙ Do not rapidly apply the brakes.
∙ Do not rapidly release the acceleratorpedal.
∙ Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a
straight course.
3. When appropriate, slowly release the accelerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from
traffic if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle. 6. Turn on the hazard warning flashers
and contact a roadside emergency
service to change the tire. For addi-
tional information, refer to “Changing a
flat tire” in the “In case of emergency”
section of this manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the bloodstream
reduces coordination, delays reaction
time and impairs judgement. Driving
af ter drinking alcohol increases the
likelihood of being involved in an acci-
dent injuring yourself and others. Addi-
tionally, if you are injured in an accident,
alcohol can increase the severity of the
injury.
5-8Starting and driving

To set cruising speed,accelerate your ve-
hicle to the desired speed, push the
COAST/SET switch and release it. The ICC
system set indicator (green), vehicle ahead
detection indicator, set distance indicator
and set vehicle speed indicator
Bwill
come on. Take your foot off the accelerator
pedal. Your vehicle will maintain the set
speed.
When the COAST/SET switch is pushed un-
der the following conditions, the system
cannot be set and the ICC indicators will
blink for approximately 2 seconds:
∙ When traveling below 20 mph (32 km/h) and a vehicle ahead is not detected ∙ When the shif t lever is not in the D (Drive)
or L (Low) (if so equipped) position
∙ When the parking brake is applied
∙ When the brakes are operated by the driver
When the COAST/SET switch is pushed un-
der the following conditions, the system
cannot be set.
A warning chime will sound and a message
will pop up: ∙ When the VDC system is off (To use the ICC system, turn on the VDC system.
Push the CRUISE ON/OFF switch to turn
off the ICC system and reset the ICC
switch by pushing the CRUISE ON/OFF
switch again.)
For additional information about the
VDC system, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
∙ When ABS or VDC is operating
∙ When a wheel is slipping (To use the ICC system, make sure the wheels are no
longer slipping. Push the CRUISE
ON/OFF switch to turn off the ICC sys-
tem, and reset the ICC system by push-
ing the CRUISE ON/OFF switch again.)
1System set display with vehicle ahead
2System set display without vehicle
ahead
Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.

5-52Starting and driving

∙ The system may not detect the ve-hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system under
the following conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance
sensor
– On steep downhill roads (the ve- hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it dif- ficult to keep a proper distance be-
tween vehicles because of fre-
quent acceleration or deceleration – Interference by other radar
sources
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the follow-
ing objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly: ∙ When snow or road spray from traveling vehicles reduces the sensor’s detection. ∙ When excessively heavy baggage is
loaded in the rear seat or the trunk of
your vehicle.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the centerline
of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime. The driver may
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.

2. AEB system warning light
AEB SYSTEM OPERATION
The AEB system will function when your
vehicle is driven at speeds above approxi-
mately 3 mph (5 km/h).
If a risk of a forward collision is detected,
the AEB system will provide an initial warn-
ing to the driver by both a visual and au-
dible alert.
If the driver applies the brakes quickly and
forcefully af ter the warning, and the AEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force. If
the driver does not take action, the AEB
system issues the second visual warning
(red) and audible warning and also applies
partial braking.
If the risk of a collision becomes imminent,
the AEB system applies harder braking au-
tomatically.
LSD2570
Starting and driving5-63

NOTE:
The vehicle’s brake lights come on when
braking is performed by the AEB system.
Depending on vehicle speed and distance
to the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may
help mitigate the consequences of a colli-
sion, should one be unavoidable. If the
driver is handling the steering wheel, accel-
erating or braking, the AEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:∙ When the steering wheel is turned as far as necessary to avoid a collision.
∙ When the accelerator pedal is de- pressed.
∙ When there is no longer a vehicle de- tected ahead.
If the AEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the
brakes are released.

erations that could cause the power steer-
ing system to overheat.
You may hear a noise when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates with the engine running, there will
be no power assist for the steering, but you
will still have control of the vehicle. At this
time, greater steering effort is required to
operate the steering wheel, especially in
sharp turns and at low speeds.
For additional information, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance will
be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
∙ While driving on a slippery surface, be
careful when braking, accelerating or
downshif ting. Abrupt braking or ac-
celerating could cause the wheels to
skid and result in an accident.
∙ If the engine is not running or is turned off while driving, the power as-
sist for the brakes will not work. Brak-
ing will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
